I've noticed many trailers with 18" wheels but, it looks like they are all running truck/car tires to get the necessary low profile sidewall heights.My guess is this is not a very good choice.It seems Vision Wheel/Tire is now making a marine hauler tire in the size 265/40/18 trailer specific/rated.The overall diameters only .2 inches bigger than 215/75/14.Anyone here tried them yet?If so what do you think of them?
